Hi guys! 
I am new to Grafana and I’m trying to get alert notifications working for some custom application metrics I’m tracking (like how long requests take and how often they error out). I can see the data just fine in Grafana, but setting up the alerts is proving tricky.
Here’s my setup: 
- Data source: Prometheus
- Metrics: Custom application performance metrics (latency, error rates)
- Goal: Email alerts when thresholds are crossed (e.g., latency above 200ms)
I have been through the Grafana documentation and tried to follow the alert rule setup steps, but the alerts just aren’t firing as expected.
Hoping you all can help with a few questions:
- Any tips for setting good thresholds for custom metrics?
- What are common mistakes to avoid when building alert rules?
- How can I test my alerts before relying on them in production?
- Can I customize alert emails to include more details about the triggered metric?
I also check this document: https://grafana.com/docs/grafana/latest/alerting/set-up/provision-alerting-resoulookerrces/file-provisioning/ But I have not found any solution. Any advice, examples, or resources would be a huge help! Thanks a bunch in advance for your time!
